8 percent

20
Q

What is critical level of necessary fat to maintain menstrual flow?

21
Q

Method of body composition assessment in which it estimate are made of bone mineral content and lean and fat mass using low energy and high energy photon beams

Hydrostatic weighing

Dual energy X-ray absorptiometry

Skin Fold measurement

Waist Circumference

Air Displacement Plethysmography

A

Dual energy X-ray absorptiometry

22
Q

What does the skinfold measurement use for the device?

A

skinfold calipers

23
Q

issues with skinfold measurement

A

will not work for obese people who have 20-40 percent of fat.
Primarily developed on young, white, healthy males

24
Q

Where is wasit circumference?

A

iliac crest/ hip bone

25
Q

circumference greater than what indicate increase risk of heart disease T2D, hypertension, hyperlipidemia for men? women?

A

102 cm and 88 cm

26
Q

How does Hydrostatic weighing work?

A

measurement of displaced water when person is completely submerge because fat tissue has lower density than muscle or bone tissue

27
Q

Problem with Air Displacement Plethysmography which is similar to hydrostatic weighing

A

Assumption that Fat free mass and fat mass is constant

bone mineral content density changes which varies throughout life cycle

28
Q

Technique of body fat assessment in which weak electrical current is measured.

Hydrostatic weighing

Dual energy X-ray absorptiometry

Skinfold measurement

Waist Circumference

Bioelectrical Impedance Analysis

Air Displacement Plethysmography

A

Bioelectrical Impedance Analysis
